solve systems of equations using substitution

This learning resource focuses on the substitution method for solving systems of linear equations. It begins by defining a system of equations as a set of two or more equations containing the same variables, with the goal of finding a solution point (x, y) that satisfies all equations. The resource provides a clear, step-by-step guide to applying the substitution method, which involves isolating one variable, substituting it into another equation, solving for the remaining variable, and back-substituting to find the other variable. Several examples are included to illustrate these steps in action, along with practice problems for students to solve. The resource also encourages collaborative activities, allowing students to work together to solve real-world problems using the substitution method, such as comparing cell phone plans. Additionally, it incorporates self-assessment and reflective components to gauge understanding and encourage critical thinking.
